Honda bulletin ATI&01082025901

Honda filed this with NHTSA as a manufacturer communication dated Jan 9, 2025, received Jan 25, 2025, about the engine. It names 1 model year (2017). A manufacturer communication is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Honda ATI&01082025901 a recall?

No. A manufacturer communication is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.

Is the ATI&01082025901 repair free?

Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.

Which vehicles does ATI&01082025901 cover?

The manufacturer filed it against 1 model year: 2017 Honda Fit. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
